1469 \`configure' configures this package to adapt to many kinds of systems.
1470
1471 Usage: $0 [OPTION]... [VAR=VALUE]...
1472
1473 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1474 VAR=VALUE.  See below for descriptions of some of the useful variables.
1475
1476 Defaults for the options are specified in brackets.
1477
1478 Configuration:
1479   -h, --help              display this help and exit
1480       --help=short        display options specific to this package
1481       --help=recursive    display the short help of all the included packages
1482   -V, --version           display version information and exit
1483   -q, --quiet, --silent   do not print \`checking ...' messages
1484       --cache-file=FILE   cache test results in FILE [disabled]
1485   -C, --config-cache      alias for \`--cache-file=config.cache'
1486   -n, --no-create         do not create output files
1487       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1488
1489 Installation directories:
1490   --prefix=PREFIX         install architecture-independent files in PREFIX
1491                           [$ac_default_prefix]
1492   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1493                           [PREFIX]
1494
1495 By default, \`make install' will install all the files in
1496 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1497 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1498 for instance \`--prefix=\$HOME'.
1499

1645 Some influential environment variables:
1646   CC          C compiler command
1647   CFLAGS      C compiler flags
1648   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1649               nonstandard directory <lib dir>
1650   LIBS        libraries to pass to the linker, e.g. -l<library>
1651   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1652               you have headers in a nonstandard directory <include dir>
1653   CXX         C++ compiler command
1654   CXXFLAGS    C++ compiler flags
1655   CPP         C preprocessor
1656   MAKEINFO    Parent configure detects if it is of sufficient version.
1657   MAKEINFOFLAGS
1658               Parameters for MAKEINFO.
1659   YACC        The `Yet Another Compiler Compiler' implementation to use.
1660               Defaults to the first program found out of: `bison -y', `byacc',
1661               `yacc'.
1662   YFLAGS      The list of arguments that will be passed by default to $YACC.
1663               This script will default YFLAGS to the empty string to avoid a
1664               default value of `-d' given by some make applications.
1665   XMKMF       Path to xmkmf, Makefile generator for X Window System
1666
1667 Use these variables to override the choices made by `configure' or to help
1668 it to find libraries and programs with nonstandard names/locations.

12691    Here is a matrix of mmap possibilities:
12692         mmap private not fixed
12693         mmap private fixed at somewhere currently unmapped
12694         mmap private fixed at somewhere already mapped
12695         mmap shared not fixed
12696         mmap shared fixed at somewhere currently unmapped
12697         mmap shared fixed at somewhere already mapped
12698    For private mappings, we should verify that changes cannot be read()
12699    back from the file, nor mmap's back from the file at a different
12700    address.  (There have been systems where private was not correctly
12701    implemented like the infamous i386 svr4.0, and systems where the
12702    VM page cache was not coherent with the file system buffer cache
12703    like early versions of FreeBSD and possibly contemporary NetBSD.)
12704    For shared mappings, we should conversely verify that changes get
12705    propagated back to all the places they're supposed to be.
12706
12707    Grep wants private fixed already mapped.
12708    The main things grep needs to know about mmap are:
12709    * does it exist and is it safe to write into the mmap'd area
12710    * how to use it (BSD variants)  */
